Emotional Language: Remember when I spoon fed you soup when you were sick? Well, the least you could do to pay me back is to pass the salt.
Cause and Effect: If you don't pass the salt, then I will have to sit here and eat salt-less, unappealing food.
Generalizations: All teenagers love to put delicious salt on their food, so why do I have to be the exception?
Rhetorical Question: Are you really just going to sit there and not pass the salt?
Downplaying: While your just sitting there, why don't you simply pass the salt to someone closer to me so you don't have to reach all the way to me?
Analogy: This food is so bland without salt that it tastes like paper. But it could turn into an exquisite meal if you just pass the salt...
